We're not gonna lie. We hate it too. 'Fat burner'. The little pot of magic pills has incited fascination and condemnation in equal measure ever since it was a thing. Rightly so, really. The category is a minefield. Skinny tea, bullshit infused it's confusing and misleading at best. Enter FEVER40. Formulated to tick all the boxes, we have created a product that ACTUALLY does what it set out to do - as long as you do too. An optimally dosed, synergistic blend of effective ingredients that will help you with your body composition goals. Increase energy, reduce cravings and turn up the HEAT. It can't do it for you but FEVER40 is Hard work's little helper. Made for progress.


Take 1 capsule initially to assess your tolerance, individual tolerance WILL vary – FEVER40 is highly dosed, don’t be a hero. Optimally, we recommend taking 2 capsules upon waking and a further capsule 6-8 hours later. Do not exceed more than 3 capsules in any 24hr period. Do not use within 5hrs of intended sleep. Ensure you stay adequately hydrated. For best results, use on a 5 day on, 2 day off cycle for a maximum of 8 weeks before taking a minimum of 4 weeks off the product entirely. Keep it fresh.

Much prefer these to PROJECT AD SHREDABULL What I would say is 1 capsule is plenty for females .... just my personal opinion.... guess everyones tolerance is different... if in doubt stay safe and when I first tried them I took a little bit out the capsule just after the horrendous effects of shreddabull ...... highly recommend along side a decent nutrition plan and I take 20 mins before I go to the gym ....

HR LABS fever

Probably the best fat burner I’ve used. Body temp is elevated and does contribute to fat loss.

Great product

The only “fat burner” that actually works
